TMJ stands for “temporomandibular joint.” This is the small, delicate joint that connects your jaw to your skull.
In contrast, TMD stands for “temporomandibular joint disorder.” This refers to a number of different issues that can cause issues with your temporomandibular joint (TMJ). TMJ refers to the joint itself, while TMD refers to the various conditions and issues that can affect the functionality of the TMJ.
Temporomandibular disorder (TMD) is a condition that causes pain and dysfunction in the jaw joint and muscles that control jaw movement. Treatment for TMD depends on the underlying cause of the disorder but may include lifestyle changes, physical therapy, splint or mouthguard therapy, and surgery.
